Drilling in Mach3 and PMPost postprocessor
« on: August 08, 2006, 09:03:05 AM »
I was wondering if anyone could tell me anything about writing g-codes for drilling with mach3.  I read the post about peck drilling, but what about the code for other types of drilling?  Can mach 3 do helical drills?

I need this because I am trying to make a postprocessor for PMPost to generate g code from powermill.  Is anyone else here using powermill or PMPost?  Does anyone already have a postprocessor for PMPost?

We only do helical Milling ...
You can have up to 6 axis at the same time...

So what does a line of g-code to do a helical drill look like?  I don't see it in the Mach manual or in the list of g-codes in mach3.

Just a series of G2 or G3's. Here's a 1/4" hole using a 1/8" tool. 1/8" depth of cut perr pass. 1/2" deep.

To drill a single peck hole I write

g81 x~ y~ z~ r~

x and y the point, z the depth and r the clear plane height.

Is there an equivalent for helical drills? a helical drill canned cycle?  I don't think there is, I'm just looking to confirm my suspicions.

Thanks for the replies

I don't think so. All the supported codes are in the manual.

What do you class as a helical drill?.

What is the application?.

post a picture or a web link of the tool you are talking about.
